Abstract

The invention relates to application of an organic metal phosphonic acid compound [Zn(t-C4H4PO3)(C5N2H6)]4 in the aspect of synergetic fire retardant and belongs to the technical field of synergetic fire retardant. The synergetic fire retardant can be used for preparing compound flame retardant for flame-retardant-modified polyamide plastics after being matched with other phosphorus series or phosphorus and nitrogen series fire retardant. The synergetic fire retardant accounts for, by mass, 4.5-16.7% of the total mass of the compound fire retardant, can effectively improve the flame retardant property of the polyamide plastics, and also improves the mechanical property of the polyamide plastics. The synergetic fire retardant is free of halogen, efficient, simple in preparing method, cheap in raw material, good in sample property reproducibility and suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of synergistic flame retardants, in particular to an organometallic phosphonic acid compound ([Zn(t-C 4 h 4 PO 3 )(C 5 N 2 h 6 )] 4 ) in the application of synergistic flame retardants. Background technique [0002] Polyamide is an important engineering plastic, which has the advantages of high specific strength and corrosion resistance, and is widely used in engineering fields such as construction, automobiles, and electronics. With the development of polymer material modification technology, polyamide engineering plastics not only meet the performance indicators of metal materials in terms of strength, but also approach metal materials in terms of high temperature resistance, fatigue resistance, and dimensional stability. It is precisely because polyamide plastics have the above advantages that they can gradually replace metal materials to reduce production costs and improve performance. However, b...
